DC-DC Converters based Integration of Grid Stability Estimation for PV Systems

In order to guarantee a quick and seamless transition among maximum power point tracking using Partial Power Converter (PPC) and Stationary Reference Frame (SRF) methods, an improved power management technique that limits the maximum feed-in capacity of Photovoltaic system has been suggested. Regardless of the irradiance levels, an operational control strategy is constantly maintained for high-performance and steady operation. it regulates overall PV output power to any desired set point, with no instability issues, and makes the PV systems always run on the near half of both the maximum power output According to the evaluation, a better PPC control with high precision, rapid dynamics, and stability improved performance. The converter and control loop are both responsible for overall power management. For the entire system, model-based performance analysis (including power and stability) is performed using MATLAB/SIMULINK
